The problem ISNT making them up its getting the lip around the outside to secure the hose to! I can make them, but i use thicker walled steel rather than the thin walled stuff you need! If you give me some OD (outside diameter)and wall thickness, i may be able to help. Also its the cost of making one offs, might be just as expensive as getting new mass produced ones off the shelf.
if you need any help PM me. Piccies would help to give me an idea of what you need
IF IT HAS A HOSE THEN IM YOUR MAN
BETTER TO BURN OUT THAN FADE AWAY!
